ARM: qemu-arm: enable RTC 

QEMU provides an emulated ARM AMBA PrimeCell PL031 RTC.

The patch sets the base address in the board include file according to the
definition in hw/arm/virt.c of the QEMU source. It defines the Kconfig
option for the existing driver, and enables the RTC driver in
qemu_arm64_defconfig and qemu_arm_defconfig as well as the date command.

We need an RTC to provide the GetTime() runtime service in the UEFI
subsystem.
